The core SanteDB applets are designed to easily be localized and branded to suit your particular deployment of SanteDB.

Localizing Your Applets

When writing your applets, there are a variety of ways to make localization and branding of your applet easier. First, in all HTML assets you can use the i18n service in Angular to localize your asset.

<strong>{{ 'my.ui.local.string' | i18n}}</strong>

It is recommended you use the manifest file and i18n service as SanteDB will pre-translate the file before sending it to the browser and will cache the result. This reduces the amount of processing power required for repeat viewing of the page.

You should then register my.ui.local.string in the applet's manifest file.

<strings lang="en">
    <string key="my.ui.local.string">My Local String</string>

If you want to fetch a string from JavaScript in the current locale, you can use the localization service

if(!valid) {

Switch Locales

By default, SanteDB will switch the current locale of the user interface to that preferred by the user when they authenticate. You can also manually set the locale by calling


When you call this, a cookie is set in the browser which controls the rendering on the server side. However, this is the lowest order of preference for the server. In short, the server will render assets using the following preference:

  1. The user's preference (stored at : UserEntity.languageCommunication) is used, if the user has no preference then,

  2. The lang cookie provided by the browser, if there is no setting then

  3. The value of Accept-Language HTTP header sent by the browser, if not sent then

  4. The configured server preference (set in the SanteDB.config.xml file)

Registering New Locales

Locales are registered using the applet manifest.xml, within the manifest, you can specify one or more assets (css, javascript, etc.) to be loaded for the particular locale. For example, to define a localization for Esperanto:

<AppletManifest xmlns="http://santedb.org/applet">
    <info id="org.santedb.sample">
    <locale code="eo">

This instructs the SanteDB application framework to register a new locale "EO" and load the two supplied assets whenever the user interface is switched to locale eo.

The locale JavaScript files can be your own settings for SanteDB specific objects or they can be included libraries from common javascript plugins.

Overriding Default Translations

The core SanteDB applets provide default translations for all core SanteDB concepts. Sometimes, depending on the context, these need to be changed. This is supported in the manifest.xml file using the priority attribute on your translation, for example, to override the default title of the Administrative Panel you could use:

<strings lang="en">
    <string key="ui.title" priority="100">My Custom Title</string>

It is recommended you never fork the core applets to change translations, this is very difficult to maintain and we cannot guarantee compatibility.

Mozilla Pontoon

You may also collect your strings in an Android style strings.xml format, this allows common tools like Mozilla Pontoon to edit your strings. In order to use this method, you should have an applet structure collecting strings under locale directories such as locales/en/strings.xml and locales/fr/strings.xml , or you may use i18n/en/strings.xml and i18n/en/strings.xml.

Once complete, you can reference your strings files in the manifest (as shown in the example below):

<strings lang="eo" extern="i18n/eo/strings.xml" />

Finally, you should create a file called i18n.toml in your applet to allow Mozilla Pontoon to import your strings.

basepath = "."
locales = [ "en", "fr", "es", "sw", "it", "my" ] 
    refernece = "i18n/en/strings.xml"
    l10n = "i18n/{locale}/strings.xml"

Once completed, you can setup a project in your Pontoon server which points to your github repository (see: Localizing your projects) and use the sync feature. The strings located in your strings.xml file should be reflected in the Mozilla Pontoon user interface where Context indicates the name of your resource string:

When you use a strings.xml file for your translations, you cannot override the default translations with priority= mechanism supported by the manifest.xml

Community Translations

SanteDB community translations are collected via the SanteDB Pontoon service. The following process is used:

  1. As the SanteDB community implements new features they add them to the appropriate strings.xml file with an English translation.

  2. Prior to a new minor release the SanteDB team merges the new terms from develop branch into the i18n branch - and the new strings become available in SanteDB.

  3. The community can contribute translations of the new strings into the i18n branch

  4. Prior to a major release the i18n branch is merged into develop(all community translations are present)

  5. The build is validated and the develop branch is merged into master where a new release is packaged.

If you would like to translate the core applets (for the administrative panel, MPI user interfaces, SanteGuard screens, or IMS) you can visit the SanteDB Community Pontoon Server
